Abstract: The structures of 2-[N-(2-chlorophenyl)carbamoyl]benzenesulfonamide and 2-[N-(4-chlorophenyl)carbamoyl]benzenesulfonamide, both C₁₃H₁₁ClN₂O₃S, are stabilized by extensive intra- and intermolecular hydrogen bonds. In both structures, sulfonamide groups are hydrogen bonded via the N and O atoms and form chains of molecules. The carbamoyl groups are also hydrogen bonded, involving the O and N atoms, further strengthening the polymeric chains running along the c and a axes in the 2- and 4-chloro derivatives, respectively. Carbamoylsulfonamide derivatives are novel compounds with a great potential for medicinal applications.

Formula: Two isomers of C₁₃H₁₁ClN₂O₃S
